  • Shielding for electrodes in photoionization detector
    Patent number: 10942061
    Abstract: A photoionization detector (100) comprises an ultraviolet radiation source (130); one or more detector electrodes (204 and 205); and a shielding material (206) located between the ultraviolet radiation source (130) and the one or more detector electrodes (204 and 205), wherein the ultraviolet radiation (240) does not directly impinge on any part of the one or more detector electrodes (204 and 205). A method for gas detection comprises exposing a photoionization detector (100) to an environment containing a target gas; and shielding the one or more detector electrodes (204 and 205) from direct impingement from the ultraviolet radiation (240) via the shielding material (206).
    Type: Grant

  • Combined radiation dosimeter and rate meter
    Patent number: 7592603
    Abstract: A radiation detector can perform both rate and dose measurements for personal safety and also to provide measurements that are sufficiently sensitive for security applications. In one embodiment, a radiation detector has a first measurement channel and a second measurement channel, where the second measurement channel can measure radiation at levels that would saturate the first measurement channel. The detector can automatically switch between the high and low sensitivity channels while continuously integrating the measured rates to determine a radiation dose. The detector can also conserve power by automatically shutting off the unused measurement channel and still give a personal safety warning when the radiation rate or the dose reaches respective alarm thresholds.
